Patented Oct. 23, 1906 Application filed March 1,1906- Serial No.303,700-

Alabama, have invented certain new and useful Improvements in Wrenches,of which the following is a specification.

.Thetype of wrenches in common use is ob- Q jectionable for manypurposes, owing to the to fact that it requires a large amount of timefor the proper adjustment of the jaws, and the quick-acting-wrencheswhich have been hitherto designed do not permitas fine an adjustment asis frequently necessary.

The object of thepresent invention has accordingly been to design awrench which embodies in one tool the great advantages ofthe two typesof wrenches just mentioned. For this purpose the movable jaw of thewrench is provided with a block one face ofwliich isthreaded so as toengage with the threaded I adjusting-rod, said block beingl slida'blymounted, so as to be quickly move.

with the adjusting rod for anyconsiderable distance.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of 0 the means foreffecting the result'reference is to be had to the following descriptionand accompanying drawings, in which Figure 1 is a perspective view ofthe wrench. Fig. 2 is a side elevation of the same, parts being brokenaway and shown insection. Fig. 3 is a transverse sectional view. Fig. 4is a longitudinal sectional view through a portion of the wrench andshows the blocks as disengaged from the adjusting- Corresponding andlike parts are referred to in the following description and indicated inall the views of the drawings by the same reference characters.

The numeral 1 designates the shank of the wrench, which is provided witha fixed jaw 2 of the conventional type at one end and the opposite end.The handle 3 is formed. with a lug 4 at the inner end thereof, whichserves as a bearing for the ad'usting-rod 5.' This threaded adjusting-r05 extends longitudinally along the shank 1 and has one end mounted inthe fixed jaw 2, while the opposite end is mountdinthelug 4...

l the block 9 out face of the shank 1 adjacent the adjustingrod 5 isformed with a groove ordepression which receives the inner portion ofthe adjusting-rod and serves as a guard to exclude dirt or other foreignmatter. A thumbpiece 6 is formed. inte ral with the adjustingrod 5', andthis thum j-pieceis shown in the drawings as bein located adjacent tothe handle 3, so as to e readil accessible. The movable jaw 7 is secureto or preferably made integral with a sleeve 8, which is slid ablymounted upon the shank 1 and also fits over the adjusting-rod 5. A block9 is mounted in one side of sleeve 8, so as to engage with the threadedadjusting-rod, the face coming into contact with the said rod beingformed with a longitudinal. depression which is threaded so as tocooperate with the threads upon the rod 5. The ends of the block 9 areprovided with tongues 10-, which slide in corresponding grooves in thesleeve 8. This construction revents any lateral displacement of the bock 9, but enables the block to be moved in and out of engagement withthe rod 5. This block 9 is connected to the movable jaw 7 b means oflinkmembers 11, one end of whic are pivoted .to said jaw, while theopposite ends are pivoted to the block by means of a'pin 12. Theextremities of the pin 12 preferably project beyond the sides of thewrench and are formed with fingerieces 13, which are preferably knurled,as s own. When thus constructed, it will be apparent that by gras ingthe finger-pieces 13. the block 9 can he moved out of engagement withthe threaded stem 5 and the movable required position it can beaccurately adthe thumb-nut 6 in the justed by turnin t will thus beunderstood usual manner. that by employing rod 5 the movable jaw 7 canbe very accurately adjusted, while be quickly moved to any desiredposition u on the shank 1. A finger-lever 17 may ,a so be employed whendesiredfor throwing of engagement with the ,adno In the preferred formofthe invention the the threaded adjustingby disengaging the :05 block 9from the rod 5 the movablejaw can sides of the block, each of the linkmembers having one end ivotally connected to the movable j aw, whi etheopposite end is loosely connected to one of the projecting ends of the 45 before-mentioned pin, and means for holding the block normally inengagement with the adjusting-rod.

3. In a wrench, the combination of a shank, a fixed jaw rigidlyconnected to one end thereof, a handle at the opposite end thereof, athreaded adjusting-rod extending along the shank and mounted between thefixed jaw and the handle, a movable jaw formed in connection with asleeve which is slidably mounted-upon the shank, a block loosely mountedin one side of the sleeve and adaptjed to engage with and cooperate withthe threaded adj usting-rod, a pin passing through the block and havingfinger-pieces at the extremity thereof, the said fingerepieces servingas a means for lifting the block out of engagement with the threadedadjusting-rod, a pair of link members located upon opposite sides of theblock, each of. the link members having one end pivotally.connected tothe (movable jaw, while the opposite end is g'loosely connected to oneof the projecting exv ftremities of the before-mentioned pin, means forholding the block normally in engage- 7o ment with the threadedadjusting-rod, and a finger-lever pivotally mounted upon the sleeve andengaging-with the block to form a second means whereby the same can belifted out of engagement with the adjustingrod.

In testimony whereof I aflix my signature in presence of two witnesses.

justing-rod 5. This lever 17 is shown as pivotally mounted between lugs15, projecting outwardly from the sleeve -8, the rear end of the leverforming a finger-piece, while the 5 forward end fits in a recess 16 inthe block 9 and engages with said block to pull the same away Irom thethreaded adjusting-rod when pressure is exerted upon the finger-piece,

Having thus described the invention, what I0 is claimed as new is 1. Ina wrench, the combination of a shank, a fixed jaw rigidly secured to theshank, a threaded adjusting-rod extendingalong the shank a movable. jawformed in connection 1 5' with a sleeve whichis slidably mounted uponthe shank, a block loosely mounted in one side of the sleeveand adaptedtoengag'e with the before mentioned threaded adjustingrod, the saidblock being formed at opposite 2o. ends with tongues which operate in.corresponding slots in the sleeve and prevent lateral displacement ofthe block, link members loosely connecting ftheblOckto the movable j aw,a spring for normally holding the block 25 1n engagement with theadjusting-rod, and a finger piece for withdrawing the block fromengagement. with theadjusting-rod.
